Sorry this is happening to you. After hours of trying to get turbotax to work, I went ahead and filed a paper return. I used many of the forms that were filled in from turbotax which helped a lot. I printed those out, but also printed out the remaining forms which related to this specific withdrawal, calculated the amounts and filled in the required numbers myself. In my case, I had to file a substitute form 1099-R to account for my broker's error in classification of type of withdrawal. I filled out form 5329 and form 4852 (the latter explains how you arrived at your numbers and what effort you made in trying to get a corrected 1099-R from your broker). Also form 8606 needs to check out. I made sure those numbers traced back to the main 1040 as all numbers in your return should obviously cross-reference. Don't hesitate to contact the IRS if you have any particular questions before you submit your return. For example, when I contacted them, they let me know that I was eligible for an additional $5k not to incur the 10% penalty because we had a baby that year and there was an Act passed called the Secure Act of 2019 that allowed for this. It's not the ideal answer you were probably hoping for with a simple click somewhere in Turbotax, but I hope this helps.
